Capacitor-run induction motors have a permanently connected phase-shifting capacitor in series with a second winding. The motor is much like a two-phase induction motor. Motor-starting capacitors are typically non-polarized electrolytic types, while running capacitors are conventional paper or plastic film dielectric types. Permeance Definition: It is the measure of the ease with which flux can be set up in a material. In other words, it measures the magnitude of the flux for the number of turns in an electric circuit.

Motors are commonly used in a variety of industrial applications, and some induction motors are key devices in assuring the continuity of processes and the production chains of many industries. However, the failure in electrical motors may be attributed to three main reasons, which cause the most common failures. Fault detection and diagnosis in induction motors is of paramount value, given the economy of scale, and the cost and time involved in the production halt and maintenance process. Mechanical faults amount to roughly 50{60% of all faults, and the air-gap eccentricity constitutes 80% of the mechanical fault [1,2].

The slit depth and width in the 56 different slitted motor models were optimized with Finite Element Method Magnetics (FEMM) software by using Finite Elements Method (FEM). The induction motor(IM), especially the squirrel-cage type, is widely used in electrical drives and is responsible for most of the energy consumed by electric motors. The IM losses can be classified as stator copper losses, rotor copper losses, iron losses, stray losses and mechanical (friction + windage) losses.

The first record of the use of concept of linear motors can be traced back to the 1840s. While the first proposal was patented in 1841 by Charles Wheatstone, the first linear induction motor (LIM) prototype was patented in 1890 [1]. Since then, linear motors are used commercially in different Single-phase induction motors have a copper or aluminum squirrel cage embedded in a cylinder of steel laminations, typical of polyphase induction motors. Permanent-Split Capacitor Motor One way to solve the single phase problem is to build a 2-phase motor, deriving 2-phase power from single phase.
